FREDERICK OSCAR HARTER AND CHARLES ALBERT PARKER, OF ILION, N. Y.

TYPE-WRITER CABINET.

SPECIFICATION forming part of Letters Patent No.360,016, dated March 29,1887.

Application filed January 3, 1887. Serial No. 223,235. (No model.)

To all whom it may concern.-

Be it known that we, FREDERICK Oscar: HARTER and CHARLES ALBERT PARKER,citi- Zens of the United States, residing at Ilion, in the county ofHerkimer and State of New York, have invented new and usefulImprovements in Type-Vriter Cabinets, of which the following is aspecification.

Our invention relates to improvements in type-writer cabinets; and itconsists in a certain novel construction and arrangement of parts, fullyset forth hereinafter and claimed.

In the accompanying drawings, Figure l is a perspective view of ourimproved cabinet. Fig. 2 is a vertical central section of same. Fig. 3is a similar view showing the case closed.

Referring to the drawings, in which similar letters denote correspondingparts in all the figures, A is the cabinet, made in the form of theordinary officedesk, either with or without the drawers A at the sides,a portion, B, of the top 0 of which desk is adapted to act as a lid, andis hinged at the rear edge, as seen at D.

E is the swinging supportingplatform for the typewriter, the front orouter side of which platform is supported upon the crossrail 6 of thedesk or cabinet when the latter is open, and the rear side of whichplatform is sustained by the cord G, which passes over a pulley, H, atthe rear of the desk or cabinet, and is attached to the weight H, movingin a vertical weight box or compartment. The specific gravity of theweight is such as to counterbalance the other moving parts, and thusinsure an easy movement thereof, as will be readily seen.

I is a bracket, secured to the upper side of the platform at one endthereof, having the gear-teeth on the upper edge, the general outline ofthe toothed upper edge being curved, as shown, with ,the front endprojected down and a stop or enlarged tooth, I, at the rear end thereof.

Secured to the under side of the lid and adapted to mesh at all timeswith the teeth on the bracket I is a gear, K, made in the form of asegment.

XVhen the cabinet is closed, the platform E rests at the outer or frontedge upon a dustexcluding strip, Lat the sides upon the inclined stripsL and at the lower or rear edge upon the shelf L This arrangementexcludes all dust from the interior of the case when closed. The frontend of the said platform is guided by the dust-strip L, which, inraising the platform, serves to direct the front edge thereof to itsposition over the rail 0.

N is a cross-bar, which is designed as astop for the rear edge of theplatform when it is in its raised position.

In order to raise the machine into position for operation without theinconvenience which might attend reaching up to raise the lid, weprovide a lever, O, pivoted to the case at P and having a handle, 0. Tothe rear end of the lever is pivotally attached a link, Q, the other endof which link is secured to the platform E.Therefore,tobringthemachineintoposition for operation, grasp the handle0 (which is within easy reach of the operator) and press down upon it.The force exerted (which need only be slight, as the counterbalancingweight H will assist the movement,) will raise the platform, the frontof which will be guided by the strip L and the rear end by the guidepinsand track. As the platform rises, the cog-teeth in the bracket 1,meshing with the teeth of the gear K, will cause the lid of the desk orcabinet to be raised. XVhen the said lid reaches a point slightly beyondthe vertical line, as seen in Figs. 1 and 2, the end of the segment Kwill bear against the stop I on the bracket I, and prevent furtherbackward movement.

If it should prove inconvenient to have the lid B in the raised positionshown while using the type-writer, it is only necessary to pressslightly down upon the platform to disengage the gears, and then the lidmay be laid entirely back, as shown in dotted lines in Fig. 2.

The same operation is necessary to re-cngage the gears.

To lower the machine,simply raise the handle O, and the platform will belowered and drawn back and the lid 13 will return to its place, operatedby means of the gears I K.

It is only necessary to have the gears on one side of the platform, asshown; but, if desired, they may beplaced on both sides. The lever 0 maybe placed on either side or on both sides of the platform, although itis only necessary to be on one side, and preferably on the same side asthe gears I K.

In the foregoing description we mention the dust-strips L and L and theshelf 1 and the cross-bar N, all of which features areincluded in ourprevious application, Serial No. 219,669, filed November 23, 1886. Wetherefore do not claim them as new herein, but include them in thepresent application to add to the general completeness of the presentcabinet.

Another advantage is that the lid may be detached and laid back out oftheway of light; or it may be provided with a clip or some similardevice and used in the ordinary or elevated position as a support forpapers, 850., to be copied.

We are aware that it is old to construct a case or cabinet in which acounterbalanced platform for supporting the type-writer is employed anda hinged lid connected by the pivoted links to the platform; but such isnot our invention, and forms no part of our claims.

Having thus described our invention,what we claim, and desire to secureby Letters Patent of the Uni-ted States, is-

1. In combination with the lid B of the case or cabinet, the platform E,said platform and lid having intermeshing gears, whereby the platformand lid are raised simultaneously and the lid may be disengaged from theplatform and thrown back entirely out of the way at will, as set forth.

2. In combination with the lid B of the desk or cabinet A, said lidhaving the gear K, the platform E, having the gear I, adapted to engagewith the gear K of the lid, substantially as described, for the purposeset forth.

3. In combination with the case or cabinet and supportingcounterbalanced platform E, the lever O, pivoted to the case or cabinetand provided with a link, Q, connected to the platform, as set forth.

4. In a cabinet or case for type-writers, the supporting-platform E,having the gear I, and the lid B, having gear K to mesh with the gear I,combined with the lever 0, connecting with the platform to raise thesame, substantially as described, for the purpose set forth.

5. In a cabinet for type-writers, the platform E, having gear I, securedthereon and formed with the stop I, combined with the lid B, having thetoothed segment K to mesh with the gear I, and held from falling back bythe said stop I, substantially as described, for the purpose set forth.

6. In a cabinet, the platform E, having gear I'and counterbalancingdevice H, combined with the lever O to operate said platform, and thelid B, provided with gear K, adapted to mesh with the gear I and raisethe said lid by the action of the platform E, substantially asdescribed, for the purpose set forth.

In testimony that we claim the foregoing as ourown we have heretoaffixed our signatures in presence of twowitnesses.
